Biological clock still ticking in 50s

CHICAGO, ILLINOIS — Feel that biological clock starting to tick? No need to worry, say researchers. There's no medical reason to prevent healthy women in their 50s from turning back their biological clocks and having babies with donated eggs, according to the biggest study of motherhood after menopause.

Researchers said older women were likely to have Caesarean births and faced high rates of pregnancy-induced diabetes and high blood pressure. But those conditions are temporary, treatable and not reason enough to exclude them from trying to get pregnant.
